1. ### An electron moving through an electric field experiences an experiences an acceleration of 6.3 x 10^3 m/s^2. Calculate the electric force...?

F = m*a = qE -----> E = m*a/q = 9.11e-31*6.3e3/1.602e-19 = 3.6e-8N/C

3. ### what is the capacitance?

capacitance C = εo*εr* A / d since εo = 8.85*10^-12 and εr = 1 (pure air in between) , then : C = 8.85*10^-12*(5.25/3.14)*10^-1 = 1.48*10^-12 ( 1.48 pF )

4. ### How can I find the initial velocity of the bullet?

Work done by the block sliding = force * distance = mass * g * uk * distance   this is equal to the initial KE of the block and bullet, KE = 1/2 * mass * speed^2   then you use the conservation of momentum to find the speed of the bullet.

5. ### Need help parallel and sereis circuits physics?

Assuming all three wires are made out of the same material you can determine the total (equivalent) resistance of the parallel wires using V=IReq and from there you can determine the total resistance of each wire using the parallel resistance equation. 1/Req...
